What are the main blanking and die processing technologies for Stepper Motor Progressive Die?

Blanking Technology
Blanking is a key step in Stepper motor progressive die, which involves cutting the raw material into a predetermined shape and size. In the production of stepper motor cores, blanking technology is mainly used to cut silicon steel sheets or other suitable materials into stator and rotor punching sheets. This step requires high precision and high quality to ensure that the subsequent lamination and assembly process can proceed smoothly.

Die Processing Technology
WEDM (Wire Cutting) Technology:
Wire cutting technology is a non-contact processing method that cuts materials by high-speed movement of fine metal wires (usually molybdenum wires or copper wires) under the action of an electric field.
In the processing of stepper motor core progressive dies, WEDM technology is mainly used to process complex die shapes and internal structures, such as cavities, holes, etc.
This technology has the advantages of high precision, high efficiency, and low loss, and is suitable for processing high-precision molds.
PG Grinding Technology:
PG grinding is a precision plane grinding technology used to process the flat parts of molds, such as mold bases, templates, etc.
Through PG grinding, extremely high flatness and surface roughness can be obtained, thus meeting the requirements of the mold for precision and surface quality.
CNC (CNC machining) technology:
CNC technology is an automated, digital processing method that controls the movement and processing of machine tools through pre-written programs.
In the processing of stepper motor core progressive dies, CNC technology is mainly used to process complex shapes and contours of molds, such as punches, concave dies, etc.
This technology has the advantages of high precision, high efficiency, and high flexibility, which can greatly improve the processing quality and production efficiency of molds.
Heat treatment technology:
Heat treatment technology is mainly used to improve the hardness and wear resistance of molds, thereby extending the service life of molds.
In the processing of stepper motor core progressive dies, heat treatment technology usually includes steps such as quenching and tempering to optimize the microstructure and performance of the mold.
Surface treatment technology:
Surface treatment technology is used to improve the corrosion resistance and wear resistance of molds, thereby protecting the molds from damage in the environment and during use.
Common surface treatment technologies include sandblasting, polishing, electroplating, etc. In the processing of progressive dies for stepper motor cores, these technologies can be used to treat the surface of the mold to improve its quality and durability.
